Ultrafast lasers, lasers that emit light pulses that are as short as a few femtoseconds, have enabled a wide-range of fundamental science and applications over the past two decades. To highlight recent state-of-the-art developments in femtosecond lasers, the Optical Society (OSA) today published a series of papers as part of an upcoming special Focus Issue on Modular Ultrafast Lasers in its open-access journal Optics Express. The issue is organized and edited by Wilson Sibbett and Tom Brown of the University of St Andrews in the United Kingdom, and focuses on developments based on solid-state, semiconductor and fiber lasers.
